You are joking but it's not a stretch for YC to in some way compensate high karma users who post on a continual basis.
I don't know what that compensation should be and I know it goes against the grain of the way things work everywhere and that people participate voluntarily (and derive their own benefit from it) but a token of thanks (of the monetary form) would be a good idea.
(And I'm not suggesting that someone with my karma level qualifies.)
